Hi Folks,

Writing all of you from Canada. Christmas has passed and not a flake of snow...amazing!

I'm putting together a budget build to replace my 8 year old system. Was going to do it about a year ago but never had the opportunity. Now I have the time and I've already started. These are the parts for my budget build. The parts with an asterisk in front are parts I have not bought yet but will be getting soon.

* Intel I3-6100 (CPU)
* Samsung 850 EVO 500gb (SSD Storage)
* Windows 10 Home 64-bit (Operating System)
EVGA GTX 950 SC (Graphics Card)
ASUS H110M-A (Motherboard)
Thermaltake Versa H15 (Case)
Crucial DDR4 2133 (2x4gb) (Memory)
Basic optical Drive

Now I have to select the proper PSU. I went to the "Extreme Power Supply Calculator" site and entered in the above information. The site returned a 289W recommended PSU.

This is what confuses me. My graphics card recommends that I have a minimum of 380W PSU even though I entered this GPU into the calculator.

Can someone explain to me why there's this discrepancy.

Based on this, I've been looking at PSU's between 430W and 500W. Although there is a nice Antec one at 350W which seems to be higher than what the "Extreme" site recommended but is lower than what EVGA recommends for that card.

And if any of you have any personal recommendations on a PSU, please let me know as well.

Thanks for the help.

Go with what's recommended. And the PSU sizes you're looking for seem good. The calculator says what you'll likely use, but higher allows upgrades and more overclocking headroom.
